ROLLER-BEARING.

Specification of Letters Patent.

Patented July 9, 1907.

' To all whom it may concern:

Be it known that l, ELLSWORTH Josnrn EDWARDS, a citizen of the UnitedStates, and a resident of Los Angeles, in the county of Los Angeles andState of California, have invented a new and Improved Roller-Bearing, ofwhich the following is a full, clear, and exact description.

My invention relates to improvements in roller-bearings, and moreparticularly to an improved means for spacing and guiding the rollersand for carrying the end thrust, and its object is to provide the samewith certain new and useful features hereinafter more fully, describedand particularly pointed out in the claims.

Reference is to be had to the accompanying drawings which form part ofthis specification, in which similar characters of reference indicatecorresponding parts in the several views, and in which Figure 1 is alongitudinal section through an axle and wheel, illustrating one formwhich my invention may assume; Fig. 2 is a plan view of the skeletonframe used to space the rollers and showing the same before it isapplied; Fig. 3 is an end elevation of the rollers and skeleton frame;Fig. 4 is a transverse sectional view through the rollers adjacent theirends, and more clearly illustrating the manner in which they aresupported in the frame; Fig. 5 is a longitudinal section through amodified form of my invention; Fig. 6 illustrates my invention asaffixed to a car axle; Fig. 7 is an end elevation partly in section ofthe form shown in Fig. 6; and Fig. 8 is a longitudinal section through amodified form of boxing to be used in connection with the formillustrated in Figs. 6 and 7.

Referring to the drawings in which similar numerals refer to similarparts throughout the several views, I have shown in Fig. 1 my inventionas applied to a common form of vehicle wheel 1 adapted to rotate on thespindle 2. The hub 3 of the wheel carries two telescoping tubes 4, 5having shoulders 4, 5 between which the part 6 of the hub is securelyheld. Pins or projections 7 may be used if desired, to prevent rotationof the tubes independent of the hub. The outer ends 'of the tubes areenlarged and the inner surface of the enlarged portions constitutes acylindrical bearing for the rollers, hereinafter to.be described, andthe inner end of each of said enlarged portions is cut at an angle toform a beveled bearing surface for the ends of the rollers.

The axle shown is the common form of vehicle axle having a taperingspindle 8, and in order to provide a cylindrical bearing surface Isecure a cylindrical bearing sleeve 9 to the spindle. .A suitablespacing collar 10 is used on the reduced end of the spindle, to fill thespace between the spindle and sleeve and hold the two rigidly together.At the ends. of the bearing sleeve beveled washers 11, 12 and dust guardwashers l3, 14 are provided. Between these, thin washers 15 may be usedif found necessary to adjust the parts by advancing trance of dust anddirt.

the beveled washers when worn. Around each bearing sleeve near the endsthereof and inclosed within the enlarged ends of the telescoping tubes 4and 5, are the rollers 16 and their spacing and guiding means 17, whichconstitute an important part of my invention and which will now bedescribed. Each roller 16 has a cylindrical intermediate portion 18constituting the main bearing surface, a rounded end 19 and a reducedspindle 20 between the main body and the ends. The spacing and guidingmeans 17 for the rollers may be formed in various ways, but in thepreferred form and the one illustrated, it is formed of two strips ofsheet metal having rectangular openings punched therein throughout itslength as shown in Fig. 2. The two side portions 22 are connected bycross-pieces 21 and between each two cross pieces each side portion iscrimped to form half of a journal box for thespindles 20 of the rollers16, leaving one side of each cross piece 21 in the plane of the centersof the rollers. Two of these strips or skeleton frames are used, and thetwo are riveted or otherwise secured together at suitable intervals oneinside of the other, so as to hold the rollers in an annular row withthe spindles of each roller held between the side portions 22, and themain portion 16 of each roller extending through the rectangularopenings between the cross pieces 21. The cross pieces of one or both ofthe strips 17 may be omitted, leaving merely two rings having crimped orbowed portions to act as journalboxes for the spindles of the rollers.

The conical or rounded ends of the rollers bear against the beveledremovable washers 11, 12, and the line around the end of the same ratherthan limiting it to a point at the center of the end, as would be thecase were the faces of the washers 11, 12 at right angles to the axes ofthe rollers. The dust guard washers 13, 14 are preferably cut awayslightly around their circumference, so that they fit partially withinthe ends of the tubes 4, 5, making a more perfect seal against the en-The end 24 of the spindle preferably extends beyond the end of thebearing sleeve 9, and by providing this end with screw threads and a nut25, all the parts may be securely held together.

Freedom from lateral movement may be secured by right angles to the axesof said rollers.

I adapt my improved bearing to the axle of a car wheel in the mannerillustrated in Figs. 6 to 8 inclusive. The beveled washer 28 fits on thecar axle 29 adjacent to the car wheel 30, and against this Washersurrounding the end of the axle is the row of rollers spaced and held inplace in the manner illustrated in Figs. 1 to 4. The boxing 31 has acylindrical recess fitting over the end of the car axle and rollers, andat the inner end of this recess is a beveled washer 32 contacting withthe outer end of the rollers. The boxing is firmly secured in the frameof the car truck 33 by bolts 34, 34, or in any suitable manner. 7 Ifdesired, the boxing may be made in two parts as shown in Fig. 8, whereone part may be detached on the line 35 without necessitating a completeseparation of the parts.

By means of the novel structure hereinbeiore described, the rollersserve the double function of acting as bearings and also in taking allend thrust. By supporting the rollers at both ends, they are always keptin alinement and in their proper place, and it is impossible for one endof any roller to get ahead of the other.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent:
